PURPOSE: To compare the age- and gender-specific testability rates for the Amblyopia
Treatment Study (ATS) HOTV visual acuity testing protocol using the electronic visual
acuity (EVA) tester in African-American and Hispanic preschool children.
METHODS: Measurement of presenting monocular distance visual acuity using the ATS
HOTV protocol was attempted in all African-American and Hispanic children aged 30 to
72 months from the population-based Multi-Ethnic Pediatric Eye Disease Study
(MEPEDS). Children able to be tested monocularly in both eyes were considered able.
Age-, gender-, and ethnicity-specific testability rates were calculated. Comparisons of
testability among different groups were performed using Chi-square analyses and the
Cochran trend test.
RESULTS: Testing was attempted on 3,126 children (1,471 African-American, 1,655
Hispanic; 50% female). Overall, 84% (83% African-American, 85% Hispanic; 86%
female, 82% male) were testable. Older children were more likely to complete testing
successfully than younger children (P < .0001). Age-specific testability in children 30 to
36 months of age, 37 to 48 months of age, 49 to 60 months of age, and 61 to 72 months
of age was 39%, 84%, 98%, and 100%, respectively. After stratifying by age, there were
no ethnicity-related differences in children testable (P = .12). Girls (86%) were slightly
more likely to be testable than boys (82%; P > .003).
CONCLUSIONS: Monocular threshold visual acuity testing using the ATS HOTV
protocol on the EVA tester (Jaeb Center for Health Research, Tampa, Florida, USA)
can be completed by most African-American and Hispanic preschool children,
particularly those older than 36 months of age. This protocol therefore may be used in
minority preschool children as an integral part of the diagnosis and management of
amblyopia and other forms of visual impairment.

The authors compared with non-cycloplegic photorefraction results of the Plusoptix
CR03 to cylcoplegic retinoscopy as a standard refaction. The was preformed in 204
children. The Plusoptix tended toward overminus in undilated children compared to
cyloplegic retinoscopy.
